Primefaces Error Page
I am trying to implement a global exception handler which will redirect the user to a generic error page whenever any exception occurs (e.g. NullPointerException,ServletException,ViewExpiredException etc.) Whenever a NPE occurs in my app, My customnavhandler breakpoint is hit and NavigationHandler code is executed, but somehow redirection to error page is not happening, the requested page remains partially rendered. Any idea what could be wrong here ? One info is that I am throwing an NPE deliberately on the requested page (which was partiallyu rendered after NPE) My faces-config.xml entry
